JungleMail | Embedded and Linked images
In JungleMail for SharePoint you can either add a picture by embedding it directly into the email content or hosting it externally and linking to it. However, there are benefits to choosing one method over the other. In this tutorial you will learn what those advantages are.
The using of linked images or the using of embedded images both have their own advantages. First we will discuss what those advantages are for linked images before considering embedded images.
Perhaps you have noticed that almost all email newsletters you get do not embed images, but link them to an HTTP address instead. These, as you may know, get blocked by default in Outlook and in some other email clients. You can see what this looks like in the example below.
However, a big advantage is that it this keeps email size down because the images do not travel with the email. You could see it like storing an image on a web page. The image in this case is located on an external source (web server or website) and downloaded into the message each time it is viewed by a recipient.
How to use Linked images in JungleMail
In JungleMail you can insert a public image URL in the Image block settings:
The linked image is then referenced in the source of the email using its respective web URL:
If you want images to appear without recipients having to click a "Click here to download pictures" button, you should opt to use image embedding. This is when an image is attached to an email and referenced using a Content-ID.
Embedded images referenced in the source of an email use the content-id (cid):
By default, image embedding is not enabled in JungleMail. To enable image embedding into email content navigate to JungleMail Site Collection Settings. You can also open these settings from the JungleMail user interface.
Enable image embedding from SharePoint into email content by activating the checkbox shown in the below image.
Note: While the practice of embedding images within the message provides a better user experience than linking to externally hosted images, image embedding increases the size of emails. This is especially true if you use more than one image. Sending performance will also be affected by this.
Using the Image Gallery
Enable image embedding if you are using the JungleMail Image Gallery to save and use images in your email campaigns and for sending newsletters to external recipients. As images in the gallery are being saved in the JungleMail Assets library on your Site Collection's root site, they are consequently set according to your default AAM address, which usually is Internal. However, if you use JungleMail for Internal communication inside your local LAN, these images could be linked (i.e. not embedded) too.
